I am not going to argue that this is not a good monitor. When I had this out of the box and turned it on it was outstanding. The quality of the picture is very obvious, with strong colours (the reds seem a little too strong, as is the green), sharp picture and a fairly good contrast ratio.
Now for the downsides.
The brightness of this monitor at 100% is far too bright. Once you turn it down to around 85% there is an audible electrical frequency whine as the back light dims. Setting it to around 64% (as suggested on some graphic design websites, and comfortable on the eyes) and it really is far too much to stand.
It also becomes very hot (maybe because it is ips, which is not necessarily a 'fault').
I also have massive concerns with the manufacturing quality. Essentially I bought this because of the pixel policy by HP, and the fact it is within their 'business' range of product hoping for good support.
I bought this around 12 months ago, 3 months after purchase 1000's of red pixels started to dance around (particularly in the black areas of the screen). I tested it on several laptops, and it was definitely the monitors fault. I then contacted HP who sent over an engineer.
Of the three times he visited, each replacement head had a dead pixel. Not acceptable. I decided to go for a refund. 9 months or so later after 'numerous' times of phoning/contacting HP I finally get the unit returned and the full amount of money back. This was due to their communication within customer service/customer relations, not their desire to provide me with a good service.
I am quite sad that I have had this much trouble, and that I had to return a potentially amazing monitor.
Sort it out HP.
